Over the past few months, I’ve tested several depth training dildos — from flexible silicone probes to more advanced fantasy sex toys Some gave me that deep, satisfying stretch I craved, while others taught me what not to do when training for endurance.
This guide breaks down the 8 best depth training dildos I’ve tried, highlighting what worked, what didn’t, and how each toy feels in real use. Whether you’re training for size, or simply curious about how deep you can safely go, this list gives you a realistic idea of what to expect
1. Anesidora Depth Training Dildo 20.8 Inches
The tapered tip made the initial entry quite manageable — good for the “first step” of depth. As I guided it in, the slim profile helped. Once past the initial rectal space, the feeling shifted: instead of “just penetration,” I felt fullness, pressure, and a subtle stretch. After about half the length, I definitely noticed the weight and length — you become aware of more of the toy than you do with a typical dildo.
Because the toy is 20.8 in (≈53 cm) long, you’re dealing with more than “just inside you” — a fair chunk remains outside, with the suction base stuck to a surface. I placed the base on the shower wall, sat into the angle, and relaxed into it. What helped: changing angles, easing the toy slowly rather than thrusting, allowing your body to accommodate the length & curve of your anatomy. As one depth‑play guide points out: “Start long, thin, and flexible… take it slow.”
What I appreciated: Because the shaft stayed smooth and slim, I could feel the “stretching fullness” rather than a wide girth forcing discomfort. After a while it became less about “how far” and more about “how it feels” — a sense of deepness, internal fullness, and something more spacious than earlier toys I’ve used.

2.Unicorn Dildo 18.11 Inches
The swirled fantasy design and that gentle taper gave me hope that this would be more than just a gimmick — and it turns out, it delivers a serious stretch.
Insertion started easy, thanks to the narrow tip. I used a ton of lube (silicone-based for longevity) and warmed up with a smaller toy. Once the first 5–7 inches went in, I felt that familiar “pull” of deep stimulation — a mix of pleasure and pressure. The swirling ridges gave a subtle texture without being overwhelming.
Midway through, I noticed the toy started pushing against internal curves — not painful, but a very “full” feeling that required deep breathing. At around the 14-inch mark, I hit a point where further depth wasn’t just about stretch — it became anatomical. My body had limits, and this toy helped me find them.
Pro tip: I curled it downward and let it press upward into me. That let the curve stimulate more zones and kept things feeling more grounded rather than poking straight through.
Price ：$58.49
✅ Pros
-
Fantastic for progressive stretch — starts small and goes long
-
Soft silicone texture feels smooth, not harsh
-
Whimsical design with real fantasy appeal
-
Deep penetration experience that’s truly next-level
-
Flexible enough to follow body curves without poking harshly
❌ Cons
- Awkward to store — needs space, not discreet

3.Deep Sea Octopus Long Tentacle
Like something you’d find in a mermaid’s dungeon. I tested the medium size (20.5 in / 52 cm), and I can confirm: this isn’t just art — it’s a toy built for deep, intense sensations.
The raised suction cups aren’t just decorative — they absolutely add stimulation. You don’t glide over them; you feel them. If you enjoy surface texture during insertion, this is heaven. If you're more into smooth toys, this might feel overwhelming at first.
The silicone is firm enough to hold shape, but soft enough to flex with your body. You can bend it into a U, curl it around furniture, or press it inward with full control. The tapered tip helps entry, and the gradual thickness lets you decide how far to go. At about halfway, I could feel a good mix of stretch + friction — not painful, but definitely not for beginners.
Once inside, the toy started working its magic. The curve helped with angling — especially for G-spot and prostate pressure. The ridges create drag in a good way — slow thrusts feel intense, and the suction cup base helps with grip even though it isn’t sticky like other suction bases.
Price ：$53.99
✅ Pros
-
Incredible texture from raised suction cups
-
Flexible but firm silicone curves naturally
-
Visually stunning, great for fantasy roleplay
-
Available in 3 sizes for gradual exploration
-
Perfect for depth & stretch lovers
❌ Cons
-
Too textured for beginners or sensitive users

4. Fantasy Cock Extra Long Octopus
This toy is an absolute trip — equal parts alien and oceanic fantasy. I tested the L size (17.7 in / 45 cm insertable) and from the moment I unboxed it, I knew it wasn’t just about length — it was about texture.
First impression: it’s soft but structured. The silicone has that jelly-like squish but doesn’t collapse on itself. I used a thick water-based lube and started slow. The tapered tip glides in easily. But the moment you pass the first few inches, you’re into textured territory — and it’s not subtle.
The ridges and suction cups drag along your walls in a way that feels like multiple fingers pulling and teasing inside. It’s definitely not a smooth ride, but that’s the point. If you enjoy strong external or internal stimulation, this toy’s for you.
By the time I reached the halfway point, the toy filled me in a way that felt oddly satisfying — like a stretch that slowly builds. At no point did it feel pokey or painful, but you do feel the fullness + friction combo intensely.
Price ：$54.99 – $149.99
✅ Pros
-
Crazy good texture: Realistic tentacle suckers = intense internal friction
-
Flexible but firm: Bends well, still keeps pressure
-
Multiple sizes: Fits beginners to size queens
-
Strong suction cup for stable, hands-free play
-
Elastic + durable silicone — doesn’t deform with use
❌ Cons
-
Very intense texture: Not for those who prefer smooth toys

5.Endoscope Smart Monster Dildo 18.7 Inches
It’s a full fantasy-tech fusion with a 1080P endoscope camera, tentacle design, OR squirting feature, and glow-in-the-dark water spray. I honestly wasn’t sure what to expect, but I took a full evening to warm up and dive into what it could really do.
What makes this one special though is the built-in camera. Once connected to the phone (worked with Android via Type-C), I was able to see inside in real time. The LED brightness is adjustable, and the image clarity was surprisingly sharp. It’s not just a gimmick — it adds a whole layer of visual arousal, especially when synced with partner play.
Tech Integration
Setup was easier than expected: download the “UseePlus” app, plug in the camera via USB/Lightning, and hit “Camera.” The connection was smooth. I could take photos and videos, though storage depends on your phone.
Downsides? The cable could be longer for more freedom, and while the camera doesn’t get hot, it does make the toy feel slightly rigid where the lens sits.
Price ：$84.99
✅ Pros
-
Built-in 1080P endoscope camera for live internal viewing
-
Tentacle texture delivers strong stimulation and fantasy realism
-
Squirting system simulates fluid play with solid range
-
Glows in the dark when exposed to light beforehand
-
Body-safe silicone, IP67 waterproof, and flexible enough for curved play
❌ Cons
- Camera area less flexible, which may limit bending during depth play
6.Dragon Scale Long Thin Dildos
The look is wild. The raised dragon-scale pattern runs down the entire shaft, and the soft silicone feels plush but structured enough to apply pressure without collapsing. It bends easily, which is a plus when you’re going deep — it won’t jab you or resist your anatomy.
The head is realistic, and that smooth taper helps start the insertion process comfortably. But as soon as the scales begin — you feel it. This toy is made for slow, grinding strokes, not fast thrusts.
Warm-up is crucial. I spent a good 20 minutes with a smaller, smoother toy and used a silicone-based lube for staying power. Once I started inserting the dragon dildo, I noticed how the texture gripped internally — not painful, but definitely noticeable. Every ridge adds a bit of drag, and I actually had to pause a few times to breathe and let my body adjust.
At full depth (about 40–45 cm insertable), the sensation changes: the stretch becomes constant, and the toy’s flexibility helps it curve with my body. I used the suction base on a shower wall and tried multiple angles — it stayed in place well. The real pleasure came not from speed but from fullness and texture grinding.
Price ：$57.99
✅ Pros
-
Excellent for deep, textured play
-
Flexible — curves naturally with your body
-
Dragon-scale texture provides intense stimulation
-
Strong suction base allows for hands-free positioning
-
Soft silicone is body-safe and pleasant to touch
-
Visually striking fantasy look
❌ Cons
-
Size may overwhelm those used to standard-length toys

7. Luuk - Black Double-Head Horse Dildo
If you're looking for something extreme — this is it. The Luuk Double-Head Horse Dildo is 40 cm of pure fantasy muscle, with two realistic heads, a massive knot, and a firm, grippy texture that doesn’t play nice — and that’s exactly why I liked it.
The toy feels hefty in your hands — just over 600g — and you immediately notice the giant knot in the middle. It looks intimidating, but the silicone is flexible enough to manage if you take your time.
The double-heads are both detailed and realistic — a nice surprise, because it gives you options. I started with the smaller head for insertion, using a ton of thick water-based lube and a long warm-up session beforehand.
The shaft is firm, textured, and not forgiving. This is not a beginner’s toy. The surface has vein-like ridges and a matte finish, which means there’s more drag — in a good way. You can feel every centimeter as it slides in, especially when you're working past the big knot. That part is intense. The stretch is real, and I had to breathe through it slowly. But once it’s in, it locks into place in a satisfying, almost primal way.
Price ： $53.99
✅ Pros
-
Extreme size & intensity — made for advanced players
-
Double-headed design adds versatility
-
Big knot offers thrilling stretch challenge
-
Textured shaft creates high-friction sensations
-
Durable & flexible enough for dynamic positions
❌ Cons
-
Not beginner-friendly — requires warm-up and patience
-
Draggy texture may require lots of lube
